1-1. What is DVM?
The DVM(Digital Variable Multi) air conditioning system is operated by a variable-capacity compressor
and is accommodated by multiple evaporators (indoor units). It is touted as the next-generation modular
system in the world of high-efficiency air conditioning. lt has undoubtedly changed the face of cooling
associated with high-storied buildings. It provides a broad range of different applications for settings such
as offices, hotels and schools. With its easy installation and simple controlling system, the DVM will more
than meet the demands of the air conditioning market.

1-2. Features of DVM
(1) Customized air conditioner
1) Up to 16 indoor units can be connected to one outdoor unit.
2) Indoor units can be combined by various methods, according to each room’s use and shape.
3) There are several indoor units which can be applied; 1-way cassette type, 4-way cassette type,
Ceiling, Duct (Low silhouette, Built-in, High pressure), Wall-mounted and Floor standing type.
(2) Comparison of DVM with conventional air conditioners

(3) Variable compressor
The world’s first PWM(Pulse Width Modulation) compressor controls the cooling & heating capacity
automatically, depending on the load.
1) Principle of the digital compressor
①
Composition
A solenoid valve is installed for compressor´s loading / unloading between the upper part of the fixed
scroll and the suction pipe.
②
Mechanism
a. When the solenoid valve is turned off, the fixed scroll is closed to the orbiting scroll (Loading),
b. When the solenoid valve is turned on, the fixed scroll is separated from the orbiting scroll (Unloading),
c. This process controls the On / Off turning of the valve, thus adjusting the capacity of the compressor.
d. The cooling capacity of the outdoor unit is controlled automatically, depending on the
number of operating indoor unit(s).

2) PWM (Pulse Width Modulation) valve
PWM valve is the valve to take away the fixed scroll by lifting up through the difference of pressure after the digital
scroll compress being connected to the outlet and inlet of suction. Therefore, the capacity of compressor is controlled
automatically according to the operation status such as loading when the valve is closed or unloading when the valve
is opened. PWM means the control of ON/OFF signal to the valve for loading/unloading.
(4) Refrigerant flow rates control
Refrigerant flow rates through the electronic expansion valve are controlled by the 2 factors, which are the
temperature difference between inlet and outlet of evaporator and the difference between room and set temperature.
a. An electronic expansion valve optimally distributes refrigerant flow rates to each room and the fuzzy logic enables
the unit to cool precisely; refer to the figure below.
b. The air conditioner senses the temperature difference between inlet and outlet of evaporator, plus the temperature
difference between room and set temperature. It calculates the superheat and the room temperature status, then
adjusts refrigerant flow rates by deciding the required steps for the valve to open.

(5) Long & single piping system
1) Piping can be extended up to 300 ft.; refer to the figure.
2) The outdoor unit is connected with each indoor unit by
single refrigerant piping.
(6) Convenient centralized control
1) Every indoor unit has its own remote controller.
In addition, a maximum of 16 indoor units
can be controlled with the centralized controller.
2) A maximum of 256 indoor units can be controlled
by using the PC Control.
(7) Easy installation
Simple planning and installation during the early
stage of building construction or renovation.
(8) Minimizing operation costs
The cooling / heating capacity is adjusted automatically
with the variable compressor, which reduces power
consumption and running costs.

◆ The system enables the connection of indoor units with a total capacity of between 50 to 130% of that of
the corresponding outdoor unit but where this capacity ratio exceeds 100% then the actual capacity of
each indoor unit will fall a little short of its individual rated capacity when all the units are operated
simultaneously.
◆ The specification of super cooler may differ, depending on the model.
